Benefits of technology

[0020](B2) a dryer to thermally treat the catalyzed carbonaceous feedstock to reduce moisture content;

Problems solved by technology

In doing so, the loss of a single component, due to failure or maintenance, in any train can require shutting down of the entire gasification train, resulting in loss of production capacity.
Each unit in the feedstock processing and gas purification and separation systems can have differing capacities, resulting in over- or under-burdening with particular units within the overall system, losses in efficiency, and increased production costs.

Abstract

Systems to convert a carbonaceous feedstock into a plurality of gaseous products are described. The systems include, among other units, three separate gasification reactors for the gasification of a carbonaceous feedstock in the presence of an alkali metal catalyst into the plurality of gaseous products including at least methane. Each of the gasification reactors may be supplied with the feedstock from a single or separate catalyst loading and / or feedstock preparation unit operations. Similarly, the hot gas streams from each gasification reactor may be purified via their combination at a heat exchanger, acid gas removal or methane removal unit operations. Product purification may comprise trace contaminant removal units, ammonia removal and recovery units, and sour shift units.
